Thereafter, the samples were subjected to the pH cycling for consecutive 21 days, and SMH was recorded. The SMH was evaluated using a Vickers microhardness tester. Statistical analysis was done using a
Tukey test for each group based on the stage of treatment and one-way ANOVA for comparison among different groups.
BAG Novamin showed SMH recovery at 96.75% followed by f-TCP at 95.83%, nHAp at 90.88%, and GSE at 48.71%. Statistically significant differences were observed between the first three groups and the rest of the groups after RML stage.
BAG Novamin, f-TCP, and nHAp showed considerable RML followed to a lesser extent by GSE.

Nano restorative composites have been successfully used in restorative dentistry and have high strength and wear resistance. Conventional orthodontic adhesives also possess optimal strength to withstand occlusal forces. This study was done to compare the shear bond strength (SBS) of orthodontic bracket after bonding with nanorestorative composite and orthodontic adhesives.
This
experimental study used sixty extracted teeth (divided into two groups). In Group A (
= 30), the brackets were bonded with Filtek Z350 (3M/Unitek, Monrovia, California, USA), a nano ceramic restorative composite, and in Group B (
= 30), the brackets were bonded with Transbond XT (3M/Unitek, Monrovia, California, USA), a conventional orthodontic adhesive. The SBS of the orthodontic brackets was measured using a universal testing machine. The modified 0-5-scale adhesive remnant index (ARI) was used to assess the amount of adhesive on enamel and bracket surfaces. The surface topography was observed to evaluate enamel damage.
The mean (standard deviation [SD]) SBS of 11.07 (1.96) Mega Pascal (MPa) was observed with Filtek Z350, whereas the group bonded with Transbond XT showed the mean (SD) SBS of 12.18 (1.69) MPa. The results showed that Transbond light curing adhesive produced higher SBS than Filtek, but the difference was statistically insignificant (
= 0.088). The comparison of ARI score between the two groups also showed statistically insignificant difference (χ
= 4.764, df = 5,
= 0.445), and most of the teeth in both groups exhibited score 3 (63%), showing the least damaging mode of bond failure to the enamel bracket interface.
There was no significant difference in the mean SBS of Filtek Z and Transbond XT adhesives. Both materials showed optimum bond strength to withstand occlusal forces.

This study aimed to assess the oral hygiene practices and oral health status of middle aged (45-55 years) women residing in rural areas of Ambala district (Haryana).
In this cross-sectional study, 79 villages were selected using simple random sampling technique through an online randomizer. EG-011 cost The study participants (780) were selected through convenience sampling and oral health status was (dental caries, periodontal status, prosthetic needs, and dental fluorosis) recorded on a self-structured format based on World Health Organization Criteria (WHO, 1997). Group comparisons were done by using Chi-square test for categorical data.
In the present study, 69.2% of the study participants used toothbrush and toothpaste for cleaning teeth. Women in the age group of 45-50 years had lower mean Decayed, Missing and Filled Teeth (7.80 ± 5.21) when compared with the age group of 51-55 years (9.77 ± 6.16). Ninety-eight percentage of the women were in need of dental prosthesis. Among the study participants, 56.5% had 4-5 mm loss of attachment (LOA) and 23.2% had 6-8 mm of LOA. Difference between the need for multiunit dental prosthesis among the age groups (45-50 years) and (51-55 years) was statistically significant (
< 0.05).
Thus middle-aged women residing in rural area have high oral care need; however, there is quite a gap between the need for dental care and the amount of dental care utilized.

This study was conducted to compare and evaluate the effect of three abutment-implant connections on stress distribution around three different implants under similar material properties and loading condition using finite element analysis (FEA).
Three different types of implant-abutment connections were selected. The features of these connections are Sample A Tri-channel internal connection (Nobel Biocare); Sample B Internal conical-hex Morse Taper (ADIN); and Sample C Internal octa-Morse taper method (Osstem). The following softwares - ANSYS Version 14.5 for FEA; Meshing software Hypermesh 11; and CATIA to produce computerized models of implants and for mandibular modeling were used. The implants were scanned with a high-quality scanner. All the above data were used to produce computerized models by CATIA software. Within the implant system, finite element method modeling was performed by implementing bonded conditions on the abutment-implant interfaces implementing four different load conditions. The computerized model was transferred to ANSYS software. A statistical analysis was done to compare the groups.
The samples were evaluated using three-dimensional FEA analysis. It was found that stress at 100 N, 100 N with 15° tilt, 300 N, and 300 N with 15° tilt was found to be highest in Sample A followed by Sample C and Sample B, and the difference was statistically insignificant.
Within the limitations of the present study, the tri-channel internal connection showed maximum stresses and least by the internal conical-hex Morse Taper and internal octa-morse taper connection.

The World Health Organization Oral Health Programme work plan 2018-2020 is to prevent the burden of oral diseases using digital technology. With 5 billion mobile phone subscribers in the world, covering over 85% of the world's population, the utilization of technology-based interventions for oral health promotion is no different. In India, numerous medical applications such as eRaktkosh and mDiabetes have been developed for the improvement of general health, whereas few initiatives such as mCessation and National Quitline services for oral health have been undertaken. Digitalization and oral health forms a crucial component in the future of oral health, which should be utilized in ensuring oral health for all.
